Grey Alien

Grey aliens, also referred to as "Greys", "Grays", "Roswell Greys", and "Zetans", are alleged extraterrestrial beings whose existence is promoted in ufological, paranormal, and New Age communities, and who are named for their skincolor. Around half of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect including their nature (ETs, extradimensionals, demons, or machines), origins, moral dispositions, intentions, and physical appearances (even varying in their eponymous skin color). A composite description derived from overlap in claims would have Greys as small-bodied sexless beings with smooth grey-colored skin, enlarged head and large blackeyes.
